Fodor's Expert Review Fort Union Trading Post National Historic Site

Built by John Jacob Astor's American Fur Company, the fort was the most important fur and bison hide trading center on the upper Missouri River between 1828 and 1867. Walk around the reconstructed grounds, which include the Trade House, teepees, and the reconstructed palisade and three-story bastions of Fort Union. Follow the easy 1-mile trail to Bodmer Overlook, named for the artist Karl Bodmer, who painted the fort from this vantage point in the early 1830s. June sees a traditional Rendezvous, with fur-trade reenactors and period music, crafts, and other demonstrations. In early August, the site also hosts a Native American arts showcase and a traditional powwow.
